[hid] 0.6 released
by Hans-Christoph Steiner 15 Jun '05

15 Jun '05

Ok, so I am finally releasing a new version of [hid] and company. There has been quite a bit added, so hopefully it was worth the wait. - added placeholder names in event types/codes to prevent segfaults when devices have mis-labeled elements - added rudimentary force feedback support in Mac OS X (more to come) - added a number of mapping objects like [hid_vector] and [hid_polar] http://at.or.at/hans/pd/hid.html .hc ________________________________________________________________________ ____ "Information wants to be free." -Stewart Brand

dancing midi values
by ingo haenlein 15 Jun '05

15 Jun '05

Hey list, i am new here and my question is related to midi routing. I wrote a patch which parses incoming mididata from an external midi controller and routes them via contoller numbers to a ladspa plugin. Everything works. Controller A controlls cutoff B resonance. My problem is, that if i tweak controller A e.g. to a value = 0 and then contoller B, which has e.g. a (former) value = 100, the value of B jumps to the value of A for a short time. After this delay B has the right (old) value. Is it possible to avoid this jumping to the previous controller state, maybe with a delay or by storing the old values? thanks. ingo.

pix_multiimage
by wolfgang schwarzenbrunner 15 Jun '05

15 Jun '05

hi... this is just a quiet basic question and just for personal information (to clear things up with the multiimage thing). i always thaught that if i load a jpg sequence to pix_multiimage, it puts the whole sequence into ram and plays it back (which of course limits the sequence lenght). my question now is if its theoratically possible to make this process dynamical so that there are alway just a few frames are sent to ram and the next few frames get sent to ram while the first few get played... and so on. well this is really just an informational question. i just want to know why its not possible. regards wolfgang

Fwd: [PD] perspective in gem
by vade 15 Jun '05

15 Jun '05

I think youd have to set your gemheads to render sequentially, and using their triggered output to reposition the camera accordingly, ie: gemhead 1 position camera, render cube, , gemhead 2, reposition camera, render cube2, etc I thought you could change your lens angle, but I cant seem to find the functionality...

Using GEM to handle native alpha channels in movies
by vade 15 Jun '05

15 Jun '05

Hi. Im having a bit of trouble getting a quicktime file with a native alpha to show up (well, to be masked) properly. Is there any specific methodology that I have to use? Specific codec/ colorspace considerations that I may not be aware of? Thanks.

send~ + switch~ bug?
by Christopher Charles 14 Jun '05

14 Jun '05

hi list. i've just encountered a problem about receiving~ from a send~ located in a subpatch which is switch~ed off. after switch~ing off, the [receive~] repeats the last 64 samples it got, over and over again, resulting in an annoying squeal. [throw~] and [catch~] do not behave this way. browsing the archive, i found that david mccallum already reported this behaviour in 2003, with pd 0.36, but unfortunately he did not get any responses. http://lists.puredata.info/pipermail/pd-list/2003-06/012334.html so i'll give it a second try, this time in 2005 with pd-0.38-4. i know, i could put a [line~] in front of the [send~] in order to fade out the volume before switch~ing off, but imho, that's just a workaround, not a fix. an example is attatched. thanks in advance charlie #N canvas 0 0 709 300 10; #N canvas 0 0 450 300 send~ 0; #X obj 173 34 osc~ 123; #X obj 174 122 send~ a; #X obj 325 35 inlet; #X obj 325 92 switch~; #X connect 0 0 1 0; #X connect 2 0 3 0; #X restore 48 96 pd send~; #X obj 48 65 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 0 1 ; #X obj 47 137 receive~ a; #X obj 47 258 dac~; #X obj 168 68 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 0 1 ; #X obj 168 260 dac~; #N canvas 0 0 450 300 throw~ 0; #X obj 173 34 osc~ 123; #X obj 325 35 inlet; #X obj 325 92 switch~; #X obj 174 122 throw~ a; #X connect 0 0 3 0; #X connect 1 0 2 0; #X restore 168 99 pd throw~; #X obj 167 140 catch~ a; #X obj 48 203 *~; #X obj 64 182 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 0 0.3 ; #X obj 168 202 *~; #X obj 184 181 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 0 0.3; #X text 250 192 1 turn on the volume; #X text 248 72 2 then use the toggles to switch the send~/throw~ on and off; #X connect 1 0 0 0; #X connect 2 0 8 0; #X connect 4 0 6 0; #X connect 7 0 10 0; #X connect 8 0 3 0; #X connect 9 0 8 1; #X connect 10 0 5 0; #X connect 11 0 10 1;
